Troubled Teen Mom star Jenelle Evans is 'so excited' about her pregnancy - and she's sharing each milestone with her fans on Twitter.
Just days after posting a picture of her 'baby bump', the 21-year-old reality TV released a sonogram of her unborn child taken at six weeks.
'Check out my ultrasound picture. I circled where the baby is located since its really hard to see,' she wrote on social networking site Sulia.

'I'm seven weeks now and was six weeks and two days when the ultrasound was done. If you look closely you can see on the bottom left hand corner it tells you how big the baby is and how far along I am. So excited!'
Jenelle has previously said the pregnancy wasn't planned, telling MTV: 'I missed a few birth control pills, and found out I was pregnant at a doctor's appointment.

'I was really surprised. This wasn't planned, but it happened, so we're taking it as we go. Courtland and I are happy and excited now.'

Her new husband Courtland Rogers announced the baby news in America's Star magazine this week despite the fact Jenelle is only in her first trimester.
Jenelle lost custody of her son from a previous relationship, Jace, three, to her mother following a string of drug scandals and arrests. Rogers's daughter JaJa is currently in the custody of his ex girlfriend.
'Me and Jenelle are so happy that she’s pregnant,' Rogers told Star, adding that the baby is due September 4
'She told me, "I’m looking forward to a second chance."'
'She thinks if she can prove that she’s a good mother, she can get Jace back,' Courtland tells Star.

Courtland is notorious for her troubled ways and has been accused of being a heroin addict in recent months.
She is currently in the middle of a vicious Twitter feud with former boss James Duffy, who recently posted an old nude picture of the reality star on Twitter, along with some extremely explicit comments.

After years of drug abuse and constant run-ins with the law, Jenelle claims to be on the right path with her new husband.
Earlier this week the new brunette, who had a breast enlargement last year, attempted to prove she had cleaned up her image by posting pictures of her new makeover on Twitter.
‘So I'm looking and feeling quite gorgeous today,’ she told her followers.
